최신 Kubernetes Security Specialist CKS 무료샘플문제 (Q65-Q70):
질문 # 65
Secrets stored in the etcd is not secure at rest, you can use the etcdctl command utility to find the secret value for e.g:-
정답：A
설명：
Output
Using the Encryption Configuration, Create the manifest, which secures the resource secrets using the provider AES-CBC and identity, to encrypt the secret-data at rest and ensure all secrets are encrypted with the new configuration.
질문 # 66
You're designing a security policy for your Kubernetes cluster to restrict container image sources. You want to allow only images from your private registry and a few trusted public registries. How would you implement this policy using Admission Webhooks and what kind of validation logic would you implement in the webhook?
정답：
설명：
Solution (Step by Step) :
1. Create Admission Webhook:
- Define a Kubernetes Admission Webhook that will intercept requests to create or modify pods.
- You'll need to create a webhook configuration and a service that will handle the validation logic-
- Example webhook configuration:
2. Implement Validation Logic (Service): - Create a service that will handle the webhook requests. This service should contain your validation logic. - The validation logic should check the container images used in the pod definitions. - Sample validation logic (Python using Flask, but you could use any language/framework): python from flask import Flask, request, jsonity import json
3. Deploy Service and Webhook: - Deploy your service and the webhook configuration. - Ensure that your service is accessible by the Kubernetes API server. 4. Test: - Create or update a pod with a container image from an allowed source. The webhook should allow it. - Create a pod with a container image from a disallowed source. The webhook should deny it.
질문 # 67
Your Kubernetes cluster is configured with a default service account with broad permissions. You need to disable this default service account to enhance security and limit access to cluster resources.
정답：
설명：
Solution (Step by Step):
1. Identify Default Service Account:
- Use the command 'kubectl get serviceaccount -n default default to identify the default service account in the default namespace.
2. Remove Default Service Account:
- You need to remove the default service account using the command 'kubectl delete serviceaccount default -n default
3. Review Permissions Check your RBAC configuration and ensure that no other roles or bindings grant unnecessary permissions to any other service accounts.
4. Create Custom Service Accounts: Create new, dedicated service accounts for each application or component that requires access to the cluster.
Assign specific roles or permissions to each service account based on its requirements.
Note: This process may require changes to your applications or configurations to use the new, dedicated service accounts instead of the default service account.
질문 # 68
SIMULATION
You can switch the cluster/configuration context using the following command:
[desk@cli] $ kubectl config use-context test-account
Task: Enable audit logs in the cluster.
To do so, enable the log backend, and ensure that:
1. logs are stored at /var/log/Kubernetes/logs.txt
2. log files are retained for 5 days
3. at maximum, a number of 10 old audit log files are retained
A basic policy is provided at /etc/Kubernetes/logpolicy/audit-policy.yaml. It only specifies what not to log.
Note: The base policy is located on the cluster's master node.
Edit and extend the basic policy to log:
1. Nodes changes at RequestResponse level
2. The request body of persistentvolumes changes in the namespace frontend
3. ConfigMap and Secret changes in all namespaces at the Metadata level Also, add a catch-all rule to log all other requests at the Metadata level Note: Don't forget to apply the modified policy.
정답：
설명：
See the Explanation belowExplanation:
$ vim /etc/kubernetes/log-policy/audit-policy.yaml
- level: RequestResponse
userGroups: ["system:nodes"]
- level: Request
resources:
- group: "" # core API group
resources: ["persistentvolumes"]
namespaces: ["frontend"]
- level: Metadata
resources:
- group: ""
resources: ["configmaps", "secrets"]
- level: Metadata
$ vim /etc/kubernetes/manifests/kube-apiserver.yaml
Add these
- --audit-policy-file=/etc/kubernetes/log-policy/audit-policy.yaml
- --audit-log-path=/var/log/kubernetes/logs.txt
- --audit-log-maxage=5
- --audit-log-maxbackup=10
Explanation:
[desk@cli] $ ssh master1
[master1@cli] $ vim /etc/kubernetes/log-policy/audit-policy.yaml
apiVersion: audit.k8s.io/v1 # This is required.
kind: Policy
# Don't generate audit events for all requests in RequestReceived stage.

# Don't log watch requests by the "system:kube-proxy" on endpoints or services
- level: None
users: ["system:kube-proxy"]
verbs: ["watch"]
resources:
- group: "" # core API group
resources: ["endpoints", "services"]
# Don't log authenticated requests to certain non-resource URL paths.

Note: log volume & policy volume is already mounted in vim /etc/kubernetes/manifests/kube-apiserver.yaml so no need to mount it.
질문 # 69
SIMULATION
On the Cluster worker node, enforce the prepared AppArmor profile
#include <tunables/global>
profile nginx-deny flags=(attach_disconnected) {
#include <abstractions/base>
file,
# Deny all file writes.
deny /** w,
}
EOF'
Edit the prepared manifest file to include the AppArmor profile.
apiVersion: v1
kind: Pod
metadata:
name: apparmor-pod
spec:
containers:
- name: apparmor-pod
image: nginx
Finally, apply the manifests files and create the Pod specified on it.
Verify: Try to make a file inside the directory which is restricted.
정답：A
